What's it like to get along with someone with a broken mouth?

There is a female doctor in our dormitory, who loses energy every day. Every night when she comes back, she always tells me that the paper can't be published, and her classmates are wonderful, because she has no friends, life is like a stagnant pool, and the topic is the same every night. Every day when I come back from my internship, I am too tired to go back to my dormitory. I always go to the classroom until about 1 1, and then climb into bed after washing. I really don't want to answer the phone.
